A bicyclist traveled with a speed of 12 km/h from a camping ground to a station, located 60 km away. Write a formula expressing

the dependence of the variable s on t, where s is the distance between the bicyclist and the station in km, t - the duration (time) of his travel in hours. Using the formula, find:

The bicyclist starts at the camp and travels 12 km/h. So in t hours, the bicyclist travels 12t km.  The remaining distance (from the bicyclist to the station) is 60 - 12t, the whole distance, 60 km minus the distance the bicyclist has traveled.

s=60-12t

Now you can answer questions such as "how far was the bicyclist from the station after 3 hours?"  Substitute 3 for t.  s = 60 - 12(3) = 60 - 36 = 24 km.

<em>Answer:</em>

s=18

<em>Step-by-step explanation:</em>

First of all, the formula is s=60-12t. thanks to the person who answered this question first (teehee)

S=distance and t=duration.

We also know that the distance is 60 km, the bicyclists's speed is 12 km/h, and the <u>duration</u> for this example is 3.5 hours.

So, using the formula, we substitute all the variables and s=18.

Thanks!

Also, for how the formula is what it is, look at the previous answer cuz yea.

Maybe this helped?

slavikrds [6]

Answer:


Step-by-step explanation:

2x - y = 8

<u> x + y = - 2 </u>

3x       = 6

3x /3    = 6/3   Dividing bot sides by 3 to find x.

x = 2

Plug in the value of x to find y.

2 ( 2) - y = 8

4 - y = 8

-y = 8 - 4

- y = 4

y = -4

The solution: ( 2, -4)

Tony buys 2 boxes of chocolates. One is 4 in. 7 in. 8 in. And 8 in. 5 in. 6 in. Which box has the larger volume?
Rufina [12.5K]

Answer:

Second box

Step-by-step explanation:

Volume (of the box) = length * width * height

Volume of first box is: 4 * 7 * 8 = 224

Volume of second box is: 8 * 5 * 6 = 240

Since 224 < 240, the volume of the second box has the larger value.
